Most of us take such pride and joy over cooking our Sunday roast chicken, but plenty forgo the super simple process of using the leftovers to make a nutrient dense, zero waste stock. This recipe, brought to you by Cornish chef James Strawbridge, shows us all how easy it is to make a rich flavoured chicken stock using minimal ingredients in no time at all, which can be stored in the fridge for a few days and used to elevate our week night meals, from curries to soups. Once you begin making stock this way, we’re sure there will be no looking back. Let us know if the secret ingredient was a pleasant surprise to you!
